It wouldn't hurt to know. But what you really need a sense of is the quality of the applicants.
At least for contractors, for the type of work that I do, I'll hear "We got hundreds of applicants and all but a dozen were not even close." We've all done it. Apply for something we're not quite ready for. Multiple that by the internet and for any given opening there is a steady and significant amount of noise.
So you're not only up against the good, you have to stand out from the bad and the ugly as well. Make sure your CV is prepared for all there. To that point, your CV isn't for finding a job. It's for getting interviews.
